I'm using this code to check click event on usercontrol.
But I get an error:
User Control:(GridFilter)

Main form:
private void Main_Load(object sender, EventArgs e)
{
GridFilter.textFilter += new Utils.GridFilter.FilterText(gridFilter);
}
protected void gridFilter(string filter)
{
string tree = treeKolekcija.SelectedNode.Text;
switch (tree)
{
case "Akcioni":
DataRow[] afrows = db.dataSetKolekcija.Akcioni.Select("Naziv LIKE '" +
filter + "%'" );
DataTable newtable = new DataTable();

You haven't assigned the Button Click event handler to the handler method
you created.

You created a Button click event Handler method, but you didn't assign it to
the Button's Click event. You need to do something like the following:
buttonTrazi.Click += new EventHandler(buttonTrazi_Click);

"On main form" is not very useful information. Where specifically does
your error happen? What causes it to happen?
Not that you should at this point really need our help. It seems to me
that the error is pretty self-explanatory. Somewhere you are using
"Utils.GridFilter.textFilter" and it requires an object reference even
though you are not providing one. You should be able to figure that one
out. If not, you really need to provide actual information that describes
the context of the error for us.

it worked fine on another control.
Now, I put it on a different control and it doesn't work.
